  • Page 13: Device Tracking Concepts And Features

    Tracking Engine The Tracking Engine, based on patented technology, powers the Nortel WLE2340. It recognizes the locale of each wireless device by matching the RF Fingerprint of the device to the RF Fingerprints it has on file for each Locale. These fingerprints are created automatically by the Tracking Engine during the calibration phase.

  • Page 14: Tracking Precision

    The Nortel WLE Tracking Engine relies on Location APs to monitor the airwaves for 802.11 traffic and report data that the Nortel WLE(2340) Tracking Engine uses to match the RF fingerprint of a device's current location to the RF finger- prints it has on file.

  • Page 15: Calibration

    Evaluator After calibration, run the Evaluator. It flags locations where the Nortel WLE2340 Tracking Engine has trouble in recog- nizing and indicates how to correct the problem. The Evaluator examines the calibration for problems such as missing, conflicting, or inconsistent data to determine if it is adequate for the Tracking Engine.

This is as simple as the creation of a few additional RF fingerprints at the transition point, or it can involve setting some advanced system parameters that adjust the Tracking Engine's internal representation of a locale's borders.

    • Four outside at the compass points This coverage ensures the Nortel WLE2340 can tell when a device moves across the physical perimeter boundary. If the RF Fingerprints are large, the location reported is fairly coarse. NN47250-504 (324122-A Version 01.01)

  • Page 19: Content Delivery

    As you test the tracking with walkthroughs, you may find that you need to add RF Fingerprints in certain transition points to enable the Nortel WLE2340 to correctly report the location of a device when it passes through the transition from one Locale to the next.

  • Page 20: Access Control

    This type of location tracking requires one RF Fingerprint per Locale. More RF Fingerprints may be used in certain tran- sition points to enable the Nortel WLE2340 to correctly report the location of a device when it passes through the transition from one Locale to the next.

  • Page 29: Placement Guidelines

    Placement guidelines The number of Location APs you can install is determined by a site survey conducted by Nortel. It is based on the size of the area to be secured and the type of tracking precision required. But regardless of the number of Location APs or tracking precision, there are two general guidelines for how Location APs can be positioned in relation to one another: •...
  • Page 30 • Location APs must be placed away from large metal objects, such as elevator shafts, and closer to ceiling height in order to minimize interference from human traffic. Note. The location of existing Location APs may be set up in contradiction to the recommendations here - for instance, highly symmetrical and in the center of Locales.

  • Page 31: Calibrating The Tracking Engine

    Calibrating the Tracking Engine Once the Location APs are deployed the next step is to capture the RF data which, the Nortel WLAN Location Engine uses to identify each locale in the area under surveillance. This process is referred to as calibration.

  • Page 32: Locales

    These problems can be addressed, as outlined in 'Fine-tuning the Tracking Engine' chapter, and then the Evaluator can be rerun and another walk through performed. This chapter explains the following: • Choosing and naming locales. • Selecting the channels on which to scan during calibration. •...

    Wrong side of border reported If you are standing near the edge of a locale, and the Nortel WLAN Location Engine Tracking Engine can't determine whether you are just inside or just outside the locale, the position reported by the Tracking Engine bounces back and forth between the locale in which you are physically standing and the adjacent locale.
